AUXILIARY PLOW.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed July 14, 1914. Serial No. 850,896.

To all whom it may concern.

Be it known that I, WILLIAM E. KUEHNE, a citizen of the United States, residing at Ripon, in the county of San Joaquin, State of California, have invented a new and useful Auxiliary Plow, of which the following is a specification, in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to an auxiliary plow for orchard use and it is intended to provide means whereby the remaining land ordinarily left between rows of trees may be broken when the last furrow or two is to be plowed adjacent the trees.

An object of the invention is to provide means whereby the cutters will rotate out of the way of the trees as soon as the plow gets to the proper place, another cutter being used to break the dirt in the next row.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there are many modifications thereof.

Figure 1 is a rear elevation of a plow having this auxiliary cutter applied thereto, Fig. 2 is a plan view of the plow showing the cutter in position thereon, Fig. 3 is a View in elevation of the plow with the max iliary cutter applied thereto looking from the land side, and Fig. 4c is a plan view of the spider to which the auxiliary cutters are secured. Fig. 5 is a rear view in elevation of a plow having a modified form of cutter applied thereto, Fig. 6 is a side elevation of the cutter and arm for securing the same, and Fig. 7 is a plan view of the cutter and arm to which it is secured.

The numeral 1 represents the beam of the plow to which is applied the usual clevis 2 for traction purposes, handles 3 and 4 extending rearwardly in the usual well known manner. At the rear the plow is provided with two standards 5 and 6 which connect the beam and mold board 7, 8 indicating the land side of the plow. All of the foregoing parts of the plow are old and well known and the-device herein is intended to be applied thereto.

Connected with the standard supporting the plow mold board is the rearwardly extending arm 9, said arm having an upturned portion 10, which revolubly supports the spider 11. It will be observed that the upturned portion 10 of the arm 9 is inclined four cutters l2, 13, 14 and 15 secured thereto at such an angle as will present one of them, (see Fig. l), horizontally to cut the ground adjacent the furrow made by the plow. Each cutter arm is provided with a stop as indicated at 16, said stop striking the short arm of a lever 17 which is pivoted at 18 on a brace 19 extending from the beam to the top of the axle 10 on which the spider rotates. The brace 19 is provided with a stop pin 20 to prevent the lever 17 from being pulled around out of place by the spring 21 which holds it normally in the position indicated in Fig. 2. The brace 19 is high enough above the spider to permit the stop 16 to pass thereunder as well as to permit the cutters 13 to 15 inclusive to pass under the same.

In use, the plow is driven along close to the trees and whenever it gets close enough to the tree for the lever 17 to strike the tree the spider will be released and will rotate 90 degrees, the rotation of the spider en abling the plow to pass the tree without cutting the roots of the same.

Figs. 5, 6 and 7 show a form of the invention in which the cutters are directly connected to the hub. In these figures 25 indicates the plow beam 26 the plow handles 27 the mold board and 28 the standard connecting the beam and mold board. The cutter arm is indicated at 29 and extends rearwardly, a brace 80 being connected with its upper end and the plow. The cutter comprises a hub 31 having four curved cutters 32 extending outwardly therefrom. In front of the cutters there is a pivoted arm 33 which is normally held in a position to be struck by the cutters as they rotate by the spring 34. The arm 33 is long enough and just far enough ahead of the cutters to touch the tree the plow is passing soon enough to permit the cutters to rotate out of the way of the tree.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows, modifications within the scope of the claims being expressly reserved.

1. The combination with a plow of an arm extending rearwardly therefrom, a hub revoluble on said arm, cutters carried by the hub, when it release the cuei 's'ft q'pa;

mit the hub to rotate 90 degrees when passing a tree.

2. The combination with a plow of an arm extending rearwardly therefrom and having:

an inclined upwardly extending shaft a hub revoluble on saidshaffl'a plurality oi cutters carried by said hub, means toihold the hub" from rotation, and a lever extending into a allowing them to rotate 90 degrees.

3. The combination with a plow of an arni' j extending rearwai' dly"therefrom and having an inclined upwardly extending shaft, a hub revoluble "on'saidshafty cutters 'carriedfby the hubwndso pos'itibnedthat oneof them will I be substantially horizontal as the plot) mov'es' forward, means to prevent the hub frommot'ating, and a lever extending into the pathj of" one of the eritters "01 releasing the cutters and permitting the rotation of the hub" when passing "a tree.

4. The combination with a plow of an arm extending" rearwardly therefrom, a hub revoluble on said arm, cutters on said hub, a

' pivoted latch to prevent the hub frorift'urh 'ing, alever connected with the latch and extending outwardly from the plow for releasing the latch and allowing the cutters/"to turn when passing a tree;
